Slaving a Plexi Project

[bmf5150]

dude,you nailed the tone for dance the night away!!!its funny i find my dimarzio super distortion with the alnico 5 does VHII the best..sounds great.everytime i try slaving a plexi into another plexi it sounds horrible. i wonder about a lead head into a jcm45 or something not so bright..

[bmf5150]

Ok what did you do to the second amp? Explain, you bypassed what to what v1 to PI?? Jesus man what can one say about your clips bro honestly??? I love that fking tone!!! and that Super Distortion W/V simply kicks ass! And hey whats up with the chops there buddy> you only been playing this shit 20 years now LOL I have bust your balls man!! To my ears sound great but what the hell do I know wait for Stan he will drill ya LOL

Excellent!!

im wating for stan and whom ever to tear it apart - i depend on it.

looking at an effects loop i took the return portion of it and wired it into v1a then straight from that tube into the in of the phase inverter - so you can look at this setup as if i had an amp with an effects loop and plugged the line out of a loaded plexi into its return.

oh and uh....i put the mistake in on purpose so you would know it wasn't the original recording of dance the night. NOT! .... and its been 30 years

LOL,thanks!!!!

So the 2nd Marshall is a tube power amp not a full amp thats why it sounds good. Dave

Re: slaving, amd I getting this right (simple version) -- A plexi-typed head feeding ANY amp as long as it's clean power?

...wondering when you were going to start heading down this path of amp slaving and post some kick-ass sounding clips and findings.

these clips RULE !!! really capture the vibe and feel of a slaved set-up

Love the run at the end of the clip ala EVH 1975.

I know this about slaving an amp ( when you get it dialed in right ) how it feels when you are playing , especially leads, seems that you can do no wrong as far as soloing.

everything responds just right , sounds just right and you can noodle practically anything and it will just sound fantastic.

I really wonder when Ed used this set-up , if he just didn't go nuts playing outside the box because, there is a whole different feel to a slaved set-up.

the whole tonal coolness factor goes up a notch.

So take an outstanding guitarist ( Rockstah ) hook him up to a killer slave rig (this current set-up) and you listen and go whoa!!!!! ...THATS BADASS.

throw an echoplex in the mix and there is really nothing more to shoot for as far as capturing that early VH sound.

I just ran my marshall into the "load" on a hotplate, line out into a Sony Power amp back into my 4x12 w/G12-65s.. simple version of what u just did and I liked it can hear a lot of the "headroom" someone mentioned in eddies sound with slaving.

[Krinkle]

Wow!

All I can say is listen to the few "Beat It" notes at 6 to 8 seconds. I was waiting for Mark to break into the slippery section that comes after it!

You can argue all you want about whether or not EVH used Allan Holdsworth's amp, or some other solid state amp, to record that tune, but money talks and BS walks. Talk about "I saw pictures" and "my Dad built that amp" all you want. That sounds identical to me. When someone posts a clip of their solid state (complete amp, not just power amp) that is better than this I'll take it back.

It's so good it surpasses the "what album does this sound like" discussion. It doesn't matter any more.

Only the hands of Ed himself could do any better. And everybody knows that Mark does Ed pretty damn good.

What speakers did you use for this clip?

[dstroud]

sounds great man! Hey, I've got some Dimarzio Super Distiortions laying around - how does one go about changing the magnet and where whould I get an A5 magnet? TIA!

Cool, I ordered 1 to give it a shot. Maybe I can find a use for my Dimarzio Super Distortions after all, thanks Mark!!!!

[SoZo]

YUP... thats it... but into another marshall ...

[ericopp]

Mark,
You're next assignment, should you choose to accept it, is to route your Wrecked Plexi into the line-in of the other "stock" slave plexi and play a bunch of Fair Warning licks: Sinner's Swing, Mean Streets, Push Comes to Shove solo...

Go easy on the reverb. The "WP" doesn't need to be dimed; around 6 or 7 would be great. No need for any GE-10, either. Just straight in.

And, if I may be so bold, please use your Les Paul.

The audience is waiting.

yes indeed. on this clip the spec of the power amp Marshall was:

input - 250k pot - to the grid of v1a which had 15k grid resistor - 15k cathode resistor - the plate resistor was two 47k resistors and from the junction of those resistors was .1u cap going straight into the phase inverter.

Ive changed a few things since then and will post another clip soon.

the main plexi being slaved is a super lead. 820/.68u on v1- .0022u coupling - 33k/500 tone stack - .68u on v2a - .022u output caps -

So what you have done with the line in on the second Plexi would be the same as pluging into the return jack on a amp having an effects loop? (say my jcm 2000).
Right?

correct minus a few values. the way i have wired amp#2 is as if it had a effects loop in it and i am plugging amp#1's line out into the return of amp#2's effects loop.

with your jcm2000 u would have afew options as i know that amp has some deep and eq shift buttons.

on your jcm once you plug a line into the effects return u will have use of the volume and presence knobs like i do now as well. be interesting to see which if any or all of your switches work.

[jerrydyer]

hhhmmm interesting I thought you left that v1a alone at first. Maybe that would be too much added sizzle? or maybe it might sound like the US Festival 83 sound. It sounded a little over the top maybe he just did a sloppy slave as in instead of changing what you did, left super led spec there .68/ 2.7k then the 002 to the phase invertor. Just a theory ..prob too hot. I just printed all this out. after the amp show anxiety goes away Im going to try all this ,,,,,, sweeeeeet !
